OX-240 Governor Elevator Speed Limit Rope Clamp Steel Wire Rope 8mm 6mm

OX-240 Governor Elevator Speed Limiter Rope Clamp Steel Wire Rope 8mm 6mm Elevator Parts Speed Limit

Product Overview

The governor is one of the most important safety devices in an elevator system. It works in conjunction with the safety gear to form a mechanical safety system. When the elevator descending speed exceeds 115% of the rated speed, the governor automatically activates and triggers the safety gear, which emergency stops the car on the guide rails to prevent a fall accident.

Key Features

· High-Sensitivity Centrifugal Mechanism: Features precision centrifugal weights or a pendulum-type triggering mechanism for rapid response, with action speed tolerance controlled within ±3%.

· Bidirectional Overspeed Protection: Some models support bidirectional protection (upward overspeed protection), complying with the latest national standards.

· Self-Resetting Design: Can be reset manually or electrically after activation, facilitating maintenance and restoration of operation.

· Sealed & Durable Construction: Housing made of cast aluminum or stamped steel plate with anti-corrosion treatment. Sealed bearings prevent dust ingress, suitable for machine room or hoistway environments.

· Integrated Electrical Switch: Built-in overspeed switch cuts off the traction machine control circuit upon activation, providing both electrical and mechanical protection.

Specifications

· Rated speed range: 0.25m/s – 2.5m/s (higher speeds customizable)

· Tripping speed range: adjustable based on roping ratio and rated speed (typically 115%–140% of rated speed)

· Sheave diameter: Φ200mm – Φ400mm

· Applicable rope diameter: 6mm – 10mm

· Material: Cast aluminum housing / Steel plate housing
